GLASS-MOLD-OPERATING MACHINE.

SPECIFICATION forming :03.143 O'.LGIS Patent N0. 678,287, dated July 9, 1901. Application filed March 30, 1901.V Serial No. 53,619. (No model.)

To a/ZZ whom it may concern:

Be it known that I, FRANK ADAM SHUNK,`

My invention is inthe nature of a laborsaving machine designed to open a mold in which a bottle or other object has been made, to remove the bottle therefrom, then close one side of the mold, then place the bottle on a stand made to receive it, and then, after material for a fresh bottle has been placed in the mold, to close the other side of the mold, which has been left open preparatory to blowing another bottle, l

My invention is designed to provide means whereby most of these operations can be quickly and successivelyperformed in a practically automatic manner, which I will now proceed to fully describe with reference to the drawings, in which"-v y Figure l is a side elevation of the machine. Fig. 2 is a plan view with the mold closed and the bottle removed to its stand. Fig. 3 is a plan view with the mold open and the bottle about to be removed. Fig. 4 isan end elevation from the left-hand side of Fig. l.

Fig. 5 is a vertical section through the moldr and its subjacent plates. Fig. 6 is a perspective View showing the internesting faces of the plates below the mold. Fig. 7 is an underneath View of a portion of the table. Fig. 8 is a perspective view of the driving-gears and clutch mechanism. Fig. 9 is a horizontal section through the bottle-carrying post. Fig. l0 is a section of the same on line 10 10 of Fig. 9. Fig. ll is a vertical section through the bottle-carrying post.

In the drawings, A represents an elevated platform upon which the glass-blower stands, and in which platform are arranged two treadles T and T', Figs.,1 and 4, connecting with mechanism below, vand ene of which serves to close the mold and the other to start the machine into automatic action.

S represents the stand or table surface of my machine, which vis supported upon legs suitably braced, as shown. This stand occupies a loweroposition than the platform A, so as to bring the .mold into proper relation Ato the glass-blower.

M is the mold, and B is the bottle, which in Fig. 1v has been transferred by the machine to its place of deposit.

The purpose of my machine is to automatically open the mold M, seize the hot bottle B, Fig. 3, andstransfer it to the position shown at B, Fig. 1, andclose the mold again, the operation being under the control of the workman through the agency of the treadles T T'.

I will now proceed to describe in detail the construction of parts and the successive 0perations by which this result is attained.

C is the main drive-pulley, which receives motion from a driving-belt connected with any suitable source or power. This pulley is rigidly fixed to a short horizontal shaft C', Fig. 8, journaled in the framework, and which shaft bears a rigidly-attached gear-Wheel O2, with two laterally-projecting pins c c.

D2 is allarger gear-wheel arranged in the same plane with C2, to be engaged thereby,

vbut having at a point cl no teeth on its periphery. When this point d is opposite the gear C2, the gear D2 is out of mesh and is not rotated. The gear-wheel D2 is rigidly iixed to a short horizontal shaft D', having on its inner end a crank D, by which motion is transmitted to the working parts of the machine at the required intervals. The pulley C, shaft C', and gear C2 are driven continuously, andthe gear D2 is connected thereto at intervals at the will of the operator, as follows: To the side of gear D2there is jointed a clutch-arm d', so as to work in a plane at right angles to that of the gear. This clutcharm is normally held out of range of contact of the pins o on gear C2 by a spring d2, but is adapted to be engaged therewith by being thrown into their plane of action by one of the treadles. When so thrown in, oneof the pins c turns the clutch-arm d and also the gear D2 far enough to cause the blank space d in its periphery to pass beyond the wheel C2vand allow the teeth of D2 to engage those of C2 and be turned thereby through a complete revolution until the blank space d comes opposite the wheel C2 again, when the wheel D2 and the automatic mechanism of the Inachine stops again. To throw the clutch-arm d into engagement with the pins c at the will of the operator, the upturned end e of a horiv zontal lever E bears against it and forces it IOO in whenever lever- E is deflected. This lever is fulcrumed in the framework to play in a horizontal plane, and its outer end is jointed to a vertical lever E', Figs. 8 and 4, fulcru med to the bottom of the platform A, and a horizontal connecting-rod E2 extends from said lever E' to the downwardly-projecting end of a T-shaped lever E3, which is fulcrumed at its center to hangers from the platform. One horizontal arm of this lever is connected by a Vertical push-rod E4 to the treadle T above the platform, and the other horizontal arm is provided with a weight E5, which normally holds the treadle up and the end c of the lever E away from the clutch-arm d'. NVhen, however, the operator desires to start the machine into automatic action, a pressure of his foot upon the treadle T throws the end e of lever E against the clutch-arm d and by forcing the latter against its spring and into range of the pins c on gear C2 causes D2,to be turned initially thereby until the teeth of D2 become engaged by those of C2 to continue the revolution.

The mold M (see Figs. 3 and 5) consists of two half-sections hinged on one side and provided on the other with horizontally-projecting yoke-arms m m', the yokes of which are of different length. The yokes consist of a radial arm having a th ree-sided loop or keeper which is adjustable lengthwise the arm by means of set-screws s. In these yokes rest friction-rollers n n' on the upper ends of vertical stems 112 n3, attached to crank-arms N N', which swing about the centers o 0', and have short shaft extensions that pass through the table and are acted upon by mechanism beneath the table to open or close the said arms N N'. )Vhen these arms swing to the open posi` tion, (see Fig. 3,) theircnds bearingthe rollers n n' act upon the yokes m m' and open the two hinged sections of the mold. The mold M rests upon a bottom plate M', which has a raised and undercut seat m2, around which the two halves of the mold are closed and which forms the base for the bottoni of the bottle. The bottom plate M' has (see Figs. 5 and 6) on its underside lugs m3, and to it I apply a plate with an oblong recess m4, which fits upon a correspondingly-raised oblong projection m5, formed on the top of an adj ust-able plate M2. This plate is made Vertically adjustable to snit the height of the bottle or other article by means of four screwstems m6, which are tapped through threaded holes in each corner of the plate and have reduced lower ends that are seated in and turn in four holes in the table S. By turning these screw-stems the adjustable plate M2 is raised or lowered to bring the mold into proper position for the arms N N' to open and close the molds.

I will now describe the devices for taking the bottle out of the mold. In middle position between the arms N N' and extending longitudinally of the table there is a slot (see Figs. 2, 3, 7, and 9) in which slides a crosshead O. On the upper side of the table, along one side of the slot, is fixed a rack-bar O', having at each end an upright straight flange O2. In the cross-head is mounted a tubular post P, adapted to rotate about a vertical axis and bearing on its lower end a segmental gear p, Figs. 9 and l1, adapted to engage with the rack and to rotate the tubular post a semirevolution as it moves back and forth. Just above the segmental gear and rigidly attached to the tubular post is a square projection p', adapted to strike against the flanges O2, Figs. 2, 3, and ll, which act as guides and stops to limit the rotation of the tubular post and to hold the lifting-arm R, which it carries, to an exact stopping-point in relation to its rotary swing. As this arm R carries the pincers R', which seize and transfer the bottle from the mold to the stand on the opposite side, the necessity for stopping this arm in an exactly opposite radial position will be apparent. The lifting-arm R, Figs. l and 11, is rigidly xed to a vertical stem R2, which extends down through the tubular post P and is acted upon by devices below the table to raise and lower it to give a lifting action to the arm to lift the bottle after it has seized it in the mold, instead of dragging it olf laterally. The pincers R on the arm R consist of two spring-arms 7 7, playing in a loop 0" on the end of the arm and embraced along their shank portion-s by a second loop r2 on the end of a rod r3, xed to the top of the vertical lever r4. This leveris fulcrumed at T5 to the tubular post, and its upper end is slotted, and through this slot passes the lifting-arm R, so as to cause the lifting-arm to partake of the rotary motion of the tubular post and also to allow the lifting-arm to have a rising-and-falling movement at the moment of picking up and depositing the bottle. When the lifting-arm is turned inwardly to the machine, its pincers occupy a position in the center of the mold, as in Fig. 3, so as to grab the neck of the bottle, and when the lifting-arm is turned outwardly from the machine said pincers are directly over a stand V, which receives the bottle. This stand is fianged and contains an asbestos mat and is carried on the top of a stem V', which bya set-screw e is held in a socketc on a projecting arm V2 from the machine. By means of the set-screw U the stand V may be raised or lowered to suit the height of the bottle or other object being molded.

In order to open and close the pincers about the neck of the bottle, each spring-jaw of the pincers is formed with a swcllr, Figs. 2 and 3, and when the loop 1'2 is forced over this swell the spring-jaws are forced together to clamp the bottle-neck in seizing the same, and when said loop r2 is drawn back from said swell the spring-jaws separate to drop the bottle on the stand V. To give this motion to the loop at the proper time in an automatic Way, there is at the inner end of the slot in the table a stationary post U, Figs. l and 2,

IOO 'l IIO erases# ing-arm enters the mold comes against the lower end of lever r2/as in dotted lines,

Fig. 1, and pushes the loop r2 over the swell on the spring-jaws, causing them to grip the bottle-neck, as in Fig. 3. f On the outer end of the table there is a corresponding post U', which rises to a higher position than U and has its end bent inwardly, so as to strike the lever r4 above its fulcrum just at the'moment that said lifting-arm is above the stand V. This contact against lever r4 forces back the loop r2 away from the swell on the spring-jaws of the pincers and allows the latter to expand to drop the bottle on stand V. The rotary movement of the lifting-arm through a halfrevolution is given by the segmental gear p engaging with the rack O', and the stopping of the lifting-arm in true alinem ent is effected by the square proj ection lo against the anges O2. The backward-and-forward movement of the cross-head and its lifting-arm in the slot in the table which carries out the aforenamed movements is effected (see Figs. l and 7) by a pitman W under the table, one end of which pitman is secured to the crank D and the other end is jointed to the bottom of the cross-head and is made with a projecting cam w, which cam, when the lifting-arm and its vertical rod is in the inner position, cornes against the lower end of the vertically-sliding rod R2 ot' the lifting-arm and gives the lift to raise the bottle slightly in the mold just before transferring it by the lateral swing t0 the stand on'the other side.

To open and close-the mold, (see Fig. 7 the axes of the crank-arms N N' have attached to them below the table rigid tappet-arms t t', which are connected by pitmen t2 t3 to cranks t4 t5 on a rock-shaft T2, which has another arm T3, thatsupports a weighted vertical rod T4', that connects with the treadle T' above the platform A. The Weight on rod T4 is to aid in opening the heavy mold. The two arms N'N, which open and close the mold-section s, are acted upon automatically to open the mold (see Figs. 7 and l) by two pins 0c fr' on the lower side of the reciprocating cross-head, which pins come in contact with the tappetarms t t and work the arms N N. When the pins a; Qc operate upon the tappets t t' on the inward movement of the cross-head, they open the arms N N and also the two sections of the mold, and when the cross-head moves back the two-pronged or double-actin g tappet t' is acted upon to close one section of the mold, the other one being left open until the glass-blower puts the material for a new bottle in it. treadle T', rocks the shaft TZ and. through connecting-rod t2 and tappeti closes the other section of the mold. To permit this independent action, the connection of pitman t3 to the other tappet t' is made by a slotted an sliding jointj.

The operation of my machine is as follows: Assuming the pincers to be in their outermos He then, at will, by pressing down position above the stand made to receive the" bottle and the gear-wheels to be out of mesh, the operator presses with his foot upon treadle T and engages the gears. The pincers now swing around and with the cross-head move toward the mold, rotary motion being imparted to the pincers by the segmental gear and rack. As the cross-head moves toward the mold the pins on the lower side of the crosshead act upon the tappets' t' and open the two sides of the mold. The pincers then, being held in alinement by the square projection and the flange on the table, enter the mold and seize the bottle by the neck, the stationary abutment-arm acting upon the lower end of the pincer-lever to cause the pincers to close upon the bottle-neck. The lifting-arm now rises slightly to lift the bottle by the engagement of the cam on the lever below the table withrthe loweriend of the lifting-rod. Then as the cross-head returns to its outermost position the rack by the side of the table-slot turns the segmental gear and rotary post, swinging the pincers around to a diametrically opposite position, the square projection on the post and the upright flange at the outer end of the slot causing the liftingarm, with the bottle, to stop immediately over the stand which receives the bottle. The pincer-lever now strikes the outer abutmentarm at a point above its fulcrum, which opens the pincers and drops the bottle on the stand. As the cross-head moves back it closes one half of the mold, and after the operator has inserted the glass for a new bottle into the mold he closes the other halt` of the mold by pressing with his foot on the treadle T.
